Logu obtained his Doctorate degree from Agricultural Entomology in 1999. For his Doctoral dissertation he worked on "Evaluation of Bacillus thuriengensis for the management of lepidopteran pests in chickpea and cauliflower. He had also worked on Evaluation of sex pheromones for the management of Helicoverpa armigera in cotton for his master’s dissertation.
Logu is serving for this Institute since 1999. He is handling national and international research projects on grain storage, monitoring of stored product insects and management of insects in food products. He is also providing consultancy and handling industry projects on insect management.
During his tenure, he conducted research in areas related to management of stored product insects in grain storage. He has developed technologies for controlling psocids in grain storage. He had also developed methods for thermal disinfestation of paddy using solar energy. He is also handling a DST sponsored project on “Design and Development of Solar Photovoltaic Powered Cold Storage System” in collaboration with NIT, Trichy. He has widely published his research findings in national and international journals and conferences.
He was a Visiting Researcher at University of Manitoba, Winnipeg, Canada for six months from May 2010 to October 2010. During that time, he worked on "Effect low and high temperatures on Callasobruchus maculatus in chickpea. He is also experienced in thermal disinfestation of flour mills.

He has visited University of Queensland, Australia for the workshop in the project on "Ensuring Food Security: Harnessing Science to Protect Our Grain Harvest from Insect Threat” during 2010 and 2012. He also conducts many outreach programmes, seminars and workshops at many places across the country to popularize food processing values to stakeholders.
He attended and presented a paper in the 11th International Working Conference on Stored Product Protection (IWCSPP 2014) held at Chiang Mai, Thailand in November 2015. He is also doing the consultancy for the industries to manage the insects in their grain and food product storage.
As Co-PI, he has visited Brunel University, London for attending the meeting of DBT sponsored Indo-UK collaborative project on “Grain Care” during January 2018.
He is operating a DST sponsored project on Design and Development of Solar Photovoltaic Cold Storage system in collaboration with NIT, Trichy.
He guides M.Tech. and Ph.D. students for their project work in the areas related to Grain storage and pest management. His area of specialization are Grain storage and Stored Product Insect Management.
